properties of sound waves
Answers
A wave is a disturbance travelling through a medium.
You already learnt a wave can be classified into two types - Longitudinal and Transverse wave.
Let us see the general characteristics of a sound wave :
(1) Sound wave propagates through a medium.
(2) Sound wave propagate with different speeds in different mediums.
(3) Sound wave is longitudinal.
(4) Sound wave has two portions - compression and rarefaction.
(5) Sound wave directly results with periodic vibration of medium particles about their mean position.
(6) A sound wave have a definite length, which is often called as "WAVELENGTH".
the property of sound waves are:-
Amplitude :- the displacement between mean and extreme position.
Frequency:- the no.of oscillation in one second.
pitch
and quality of sound tone.
